LAK2G221MELB35

The LAK2G221MELB35 is a Nichicon LAK series snap‑in aluminum electrolytic capacitor rated 220 µF at 400 V. It is a radial, can‑style, polarized capacitor designed for general‑purpose power applications and for equipment exposed to fluctuating supply voltages.

Engineered for high‑temperature operation and extended ripple endurance, this part delivers 2000 hours of rated ripple‑current performance at 105°C and includes safety features for abnormally excessive voltages. The device is RoHS compliant.

Key Features

• Capacitance and Voltage — 220 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance, suitable where high DC voltage handling is required.
• High‑Temperature Endurance — Rated for operation from −25°C to +105°C with endurance specified as 2000 hours at 105°C under DC bias plus rated ripple current.
• Snap‑In Radial Can Package — Snap‑in terminal, radial can package for robust mechanical mounting in power assemblies and chassis installations.
• High Ripple Capability — Rated ripple current up to 900 mA at 120 Hz and 1.035 A at 10 kHz, supporting demanding ripple environments.
• Improved Safety for Abnormal Voltage — Designed with enhanced safety performance and a pressure relief vent to operate safely under abnormal overvoltage conditions.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU,(EU)2015/863).

Typical Applications

• General‑purpose power equipment — Used where a high‑voltage, polarized electrolytic capacitor is required for bulk capacitance in power circuits.
• Equipment operating with fluctuating supply voltages — Suited for systems exposed to voltage variation thanks to improved safety features and wide voltage support.
• High‑temperature environments — Applicable where sustained elevated ambient temperatures up to 105°C are expected, backed by 2000‑hour ripple endurance at 105°C.
• High‑ripple circuits — Appropriate for circuits with significant AC ripple due to specified ripple current ratings at 120 Hz and 10 kHz.

Unique Advantages

• Long ripple endurance: 2000 hours at 105°C under rated ripple current reduces maintenance and replacement frequency in high‑stress environments.
• Wide high‑voltage support: Part of a series offering extended voltage ranges (including 400 V), enabling selection for higher DC bus designs.
• Enhanced safety handling: Built‑in pressure relief and safety performance mitigate hazardous failure modes under abnormal excessive voltage.
• High ripple current capability: Specified ripple current at both 120 Hz and 10 kHz supports a range of power‑conversion and filtering applications.
• RoHS compliance: Meets current RoHS requirements for use in regulated markets and product lines.
